The piping limited by a Node and a Break, Node and Connector, two Nodes, two Breaks, two Connectors or a Break and a Connector. The last five providing there are no Breaks or Connectors in between. In the last three cases the Segment will coincide with a Piping Branch (from http://data.posccaesar.org/rdl/RDS267704).Association to SourceItem (PipingSourceItem)Association to SourceNode (PipingNode)Association to TargetItem (PipingTargetItem)Association to TargetNode (PipingNode)

<Item> – OPC UA Object(s) that are part of the Object Type.

<Connection> – OPC UA Object(s) that are part of the Object Type.

FlowDirectionSpecialization – A specialization indicating if the PipingNetworkSegment enables dual flow or not.

HeatTracingTypeSpecialization – A specialization indicating the heat tracing type related to the PipingNetworkSegment.

PrimarySecondaryPipingNetworkSegmentSpecialization – A specialization indicating whether the PipingNetworkSegment is a primary or secondary PipingNetworkSegment.

InsulationThickness – The insulation thickness of the PipingNetworkSegment.

LowerLimitHeatTracingTemperature – The temperature that a heat tracing system must ensure for the PipingNetworkSegment.

SiphonSpecialization – A specialization indicating if the PipingNetworkSegment is a siphon or not.

PressureTestCircuitNumberAssignmentClass – The number of the pressure test circuit of the PipingNetworkSegment.

InsulationTypeAssignmentClass – The identification code for the insulation type related to the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.

ColorCodeAssignmentClass – The color code of the PipingNetworkSegment, represented as a string.

PipingClassCodeAssignmentClass – The identification code of the piping class of the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.

NominalDiameterTypeRepresentationAssignmentClass – A readable representation of the type of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.

SlopeSpecialization – A specialization indicating if the PipingNetworkSegment is sloped or not.

NominalDiameterStandardSpecialization – The nominal diameter of the PipingNetworkSegment, given as a reference to a nominal diameter standard and value.

SegmentNumberAssignmentClass – The segment number of a PipingNetworkSegment. Values are typically (but not necessarily) string representations of numbers with a prefix.

OperatingTemperature – The operating temperature of the PipingNetworkSegment.

HeatTracingTypeAssignmentClass – The heat tracing type related to the PipingNetworkSegment, represented as a string.

JacketedPipeSpecialization – A specialization indicating whether the PipingNetworkSegment is jacketed.

FluidCodeAssignmentClass – The identification code of the fluid related to the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.

Inclination – The inclination (slope) of the PipingNetworkSegment in percent.

NominalDiameterNumericalValueRepresentationAssignmentClass – A readable representation of the numerical value of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.

NominalDiameterRepresentationAssignmentClass – A readable representation of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.

BasfLineClassAssignmentClass – The BASF line class of the PipingNetworkSegment, represented as a string. Note: This attribute has been included as an example for a company-specific attribute. It should actually be identified by a company-specific RDL reference. As there is currently no BASF RDL, the DEXPI RDL is used.

OnHoldSpecialization – A specialization indicating if the PipingNetworkSegment is on hold or not.
